RC1608F9534CS Equivalent & Substitute Parts Reference

Part Overview

The RC1608F9534CS is a 9.53 MOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0603 (1608 Metric) package format. This component is rated for 0.1W (1/10W) power dissipation with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Equivalent and substitute parts are identified when components share identical electrical specifications, mechanical compatibility, and regulatory compliance. Alternative sourcing becomes necessary to address supply chain continuity, inventory availability, or application-specific requirements such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F9534CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (9.53 MOhms), tolerance (±1%), power rating (0.1W), and temperature coefficient (±100ppm/°C) must be identical.

Mechanical Compatibility: Package designation (0603 / 1608 Metric) ensures PCB footprint and assembly process compatibility. Physical dimensions and termination count (2 terminations) must align with board design specifications.

Environmental & Regulatory Compliance: Operating temperature range (-55°C ~ 155°C), moisture sensitivity level (MSL 1), RoHS3 compliance, and REACH status must match or exceed the original specification.

Composition & Construction: Thick film construction is the specified technology. Substitute parts must maintain this composition to ensure performance consistency.

The CRCW06039M53FKEA from Vishay Dale meets all substitution criteria while adding automotive AEC-Q200 qualification, making it suitable for applications requiring enhanced reliability documentation.

Parameter Comparison

Engineering Selection Recommendations

Both the RC1608F9534CS and CRCW06039M53FKEA are functionally equivalent for standard applications. Selection between these parts is based on application requirements and supply availability:

RC1608F9534CS (Samsung Electro-Mechanics): Select this part for general-purpose applications where automotive qualification is not required. Current inventory of 903 pieces supports immediate deployment.

CRCW06039M53FKEA (Vishay Dale): Select this part for automotive applications or systems requiring AEC-Q200 qualification documentation. The higher inventory level (33,602 pieces) provides extended supply security. Physical dimensions (1.55mm L x 0.85mm W, 0.50mm max height) are within acceptable tolerance of the original specification (1.60mm L x 0.80mm W, 0.55mm max height).

Both parts maintain identical electrical performance, temperature stability, and regulatory compliance. Interchangeability is confirmed at the PCB assembly level for non-automotive applications. Automotive applications must specify AEC-Q200 qualification requirements explicitly.

Frequently Asked Questions (FAQ)

Q: Can CRCW06039M53FKEA replace RC1608F9534CS in any application?

A: Yes, for electrical and mechanical compatibility. The CRCW06039M53FKEA meets all specified parameters including resistance, tolerance, power rating, package, temperature range, and regulatory compliance. Physical dimensions are within acceptable manufacturing tolerances for 0603 package footprints.

Q: What is the significance of AEC-Q200 qualification on the Vishay part?

A: AEC-Q200 is an automotive industry standard qualification that documents enhanced reliability testing and quality assurance. This certification is required for automotive applications but is not necessary for consumer or industrial applications. Both parts are functionally equivalent for non-automotive use.

Q: Are there any thermal performance differences between these parts?

A: Both parts share identical temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C). Thermal performance is equivalent. Minor physical dimension variations do not affect thermal dissipation characteristics in 0603 package applications.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level. These components can be stored indefinitely without moisture bake-out requirements prior to soldering. Both parts carry this rating, confirming equivalent moisture handling requirements.

Q: Are both parts ROHS3 compliant?

A: Yes. Both RC1608F9534CS and CRCW06039M53FKEA are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronics manufacturing.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, for non-automotive applications. Both parts use identical 0603 (1608 Metric) package designation with 2 terminations. PCB footprints are compatible. For automotive applications, design documentation must specify AEC-Q200 qualification if required by system specifications.
